I'm saying it doesn't suit your purposes either. You are assuming that all meals at a given restaurant have the same effect. This assumption is untrue, and this means that any prediction you make based on your interpretation will also probably be untrue.
They just made the same incorrect inference that you did, that's all, but they did so more politely. In my response, which I linked for you earlier in this thread, I pointed out one way my original comment took those complexities into account in what you evidently think is my Grand Unified Theory of Restaurant Hedonics.
Well, it's too bad it doesn't suit your purposes. I hope you find an interpretation you like better!
